WebThe first parameter to attachInterrupt() is an interrupt number. Normally you should use digitalPinToInterrupt(pin) to translate the actual digital pin to the specific interrupt number. For example, if you connect to pin 3, use digitalPinToInterrupt(3) as the first parameter to attachInterrupt(). Board. Digital Pins Usable For Interrupts. racc stsThe way this works is that when an interrupt happens on an enabled port and pin, the AVR chip calls the ISR that you have configured for that event: So when an interrupt happens, how do you know which pin(s) caused the ISR? Let's assume you used a single ISR to handle all 3 ports. At this point you know only that an interrupt happened somewhere. shockwave chairWebMay 5, 2024 · Hi!
